Abstract: PURPOSE:To eliminate an interlayer insulating film from being polished to decrease its withstanding voltage in the step of forming multilayer interconnection by forming a silicon nitride grown by a plasma having low polishing rate as a stopper when burying aluminum in an electrode window by utilizing the polishing. CONSTITUTION:First layer wirings 12 are formed similarly to a conventional example on a base such as a silicon substrate 11, phosphorus, silicate glass (PSG) is grown 1.0mum thick, and the surface is flattened. A silicon nitride film 16 is formed approx. 1,000Angstrom  thick on an insulating film 13, and a plasma growth method which can be executed at approx. 450 deg.C is used to grow it. An electrode window 14 is formed at next stage, an aluminum film 15 is formed 1.5mum thick, and the film 15 is polished. Thus, the silicon nitride film is formed to polish it without affecting the distribution of the polishing to improve the working efficiency, thereby preventing the PSG from being polished not to impair interlayer withstanding voltage characteristics.

Title: Frequency multiplier
Inventor: IWATSUKI MASANORI
IPC: H01P1/203
Filed: 1988-03-11
Abstract: PURPOSE:To reduce the conversion loss over a wide range of frequency and to increase the D/U (desired signal level/undesired signal level) of an output signal by using a band pass filter BPF which transmits the desired multiplied frequency component and reflects other frequency components with the control possible with the phases of the reflected components. CONSTITUTION:The basic frequency component emerging at the output side of a multiplying element 5 is partly reflected by an output side impedance matching box 3 and mostly reflected by a BPF6. In this case, the fine control is required to some extents for the phase length theta between the element 5 and the filter 6. The filter 6 defines the reflected point of the basic frequency component as its open point. Thus this open point position is controlled so that the conversion loss is reduced over a wide range of frequency and at the same time the D/U is increased.

Title: Recognizing and processing system of on-line character
Inventor: KOTAKA KAZUMI
IPC: G06K9/62
Filed: 1981-04-17
Abstract: PURPOSE:To prevent the lowering of the recognizing capacity due to an incorrect order of writing strokes or an erroneous number of strokes without increasing the memory capacity, by dividing each stroke into an optional number of segments and approximating these divided segments to each other at a feature point of stroke of a standard pattern. CONSTITUTION:A segment dividing device 2 receives a number N of divisions of a segment number storage device 3 that gives an indication for the number of divided segments of each stroke of an input character and divides the signal 101 and the stroke of each input character into N units of segments. A pattern matching device 7 calculates the distance between strokes between the standard pattern of a picture S and the input character having R units of segments. Then the segment that has the shortest distance between strokes is decided for each stroke of the standard pattern. The total sum of the inter-stroke distances is divided by the stroke number (n) of the input character and the stroke number N of the standard pattern to obtain the distance between the input character and the standard pattern. This value of distance is delivered to a discriminating device 10.

Abstract: PURPOSE:To reduce both the frequency and the time of an clearance work related to a transmission error, by detecting the timing from a code word consisting of an algebraical rule to set the phase of a receiving clock, and at the same time, by correcting a received code word. CONSTITUTION:A code word consisting of an algebraical rule and supplied to a receiving terminal (d) is fed to a synchronizing shift register SR14 and a buffer register BR12 respectively. Then the SR14 divides the fed code by a prescribed generated polynominal and delivers the remainder. When a synchronism detecting circuit 13 detects that the output of the SR14 is reduced to O. a multi-phase clock generating circuit 16 is reset with the output of the circuit 13. Then a clock showing the end time of a 1-frame code is delivered from the circuit 16, therefore, the contents of the CR14 are transcribed to an SR11 having the same logical constitution as the SR14. Thereafter, the received code delivered from the BR12 is corrected and transferred to a BR17. The output signal of a resetting circuit 15 is delivered to the SR14 in order to clear the remainder of the SR14 for execution of a transmission frame which is received subsequently.
